Application filed June so, 1924. Serial No. 723,280.

My .invention relates to a new and useful improvement in a storage battery post clamp adapted for connecting the conducting wires to the terminals, or posts, ofa. storage battery, and has for its object the provisionofi attaching'means of this nature which may class mentioned having resilient means for carrying one of the engaging jaws of the clamping device to compensate for variations in the diameters of the battery post to assure a rigid and tight connection at all times the device is mounted on the battery ost. p Another object of the invention is the provisionof a battery post clamp having a clamping jaw associated with an operating projection and a co-operating jaw provided with resilient attaching means adapted for mounting in the handle bearing jaw.

Another object of the invention is the provision of a clamp of this nature which will permit of quick and easy assembling of the various parts, and so constructed that the parts may be varied relatively to each other depending upon the size of battery post, with which the same may be used.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood from a reference to the accompanying draw ings which form a part of this specification and in which,

Fig. 1 is a longitudinal, vertical, sectional view of the invention in clamping engagement,

Fig. 2 is a longitudinal, vertical, sectional view of the invention mounted on a battery post, preliminary to'the clamping engagement. I

Fig. 3 is a top plan view of the invention.

In the present invention, the improvement resides particularly in the method of attaching one of the clamping jaws. to the handle carrying jaw. The device is used with the battery7, having the usual battery post 8, and comprises a handle bearing aw 9, provided with a tubular pro ectlon or handle 10, s lit on one side, as at 11, for the reception 0 the terminal wires 12, which may be soldered in the device. if desired. The head 9 is provided with-a beveled or cutaway undersurface 13, to permit the assembly of the device well down toward the base of the post. The face of the head 9 is formedwith a pair of arcuate portions ter-' 'mmatmg in a substantially-flat projection.

The head 9 is provided with an opening 14 in which are positioned the inwardly turned ends 15 and 16 of a wire loop 17, which is pro ected through an eyelet- 18 of a jaw 19, having a suita give body to the eyelet and provided with a groove 20, in which the wire 17 may rest. The engaging face of the jaw 19 is formed arcuate and provided, adjacent its opposite ends with beads or ribs 21- and 22, which are adapted to engage the terminal post 8, which is generally made of lead or some similar soft material, so that the beads 21 and 22, being pressed in the post, serve to make a tightand rigid connection. i

It is preferred to form the wire 17 from some sprlng metal, so as to give sufiicient resiliency to the same to permit of slight variatlons in the diameters of terminal posts of standard make batteriesl It is of course, essential that this wire'be of suliicient tensile strengthand rigidity to resist anynormal strain which may be placed on it, when the same is used for performingthe functions intended. I

With a battery post clamp of this construct1on, the jaws 19 and the head 9 may all be formed of a'uniform size and wei ht for battery posts of different make batteries, so that these parts may beused with battery posts irrespective as towhatthe diameters may be. This is, of'course, within certain limits depending upon the efliciency with which the arcuate engaging surface of the jaw 19 may engage the terminal post. However, in most batteries, the variations in the diameters of the terminal posts are slight, so that suflicient variation may be formed in the battery post clamps by moving slightly the location of the hole 14. In this way, the wire 17 is also of a standard make, thus facilitating the. manufacture of the article, and resulting in economy besides adding to the utility of the device.

1e lug formed thereon to v In mounting the clamp on the battery shown in Fig. 1, the outwardly projecting the preferred form of structure, I do not wish to limit myself to the precise form of structure shown, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A battery post clamp comprising an engaging head; a co-ope'rating jaw adapted for clam-ping, with said head, a battery post;

and a wire member adapted for embracing said jaw and having the ends thereof angularly turned for entering an opening formed in said head.

2. A batter post clamp comprising an engaging hea a co-operating jaw; a lug formed on said jaw and provided with an opening formed therein, said jaw having a semi-circular groove on its outer surface; and a wire member adapted for projecting through the opening formed. in said lug and for lying in said groove, the ends of said wire member being angularly turned toward each other and adapted for engagement in an opening formed in said head for retaining said j aw in co-operative relation thereto.

3. A battery post clamp comprising an engaging head, having, an opening formed therein; a co-operating jaw having ribs formed on its engaging face; a lug formed on the outer surface of-said jaw and pro vided with an opening therein registering with a groove formed on said jaw; and a wire member adapted for projecting through said opening and lying in said groove, the ends of said wire member being angularly turned inwardly toward each other, and adapted for engagement in the opening of said head.

4:. A battery post clamp comprising an engaging head; a co-operating jaw; a lug formed on said jaw and provided with an opening formed therein; a wire member projected through said opening in said lug, said jaw being loosely positioned on said wire member, the ends ofsaid wire member being angularly turned toward each other and adapted for engagement in openings formed in said head for mounting said jaw pivotally in co-operative relation to said head. 7

In testimony whereof I have signed the foregoing specification.
